Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.


L-FIN:

Structure:

  • L-Fin has a base and tension wound on knurled tube material.
  • The L shaped base provides a large surface area for efficient heat transfer due to greater contact between tube and fin.
  • Fins that are completely in contact with airstream can transfer heat at lower temperature at the maximum rate and thus have higher durability.

Advantages:

  • We design L-fin for all kinds of air conditioners,heat pumps,refrigeration systems.
  • Zero leakage and tolerance to high pressure are some of the key features that are ensured during production.
  • It is 100% connected to pipe.
  • It saves electricity consumption upto about 40%.
  • Saves Ammonia gas upto about 40%.
  • Saves pipe upto about 40% since it requires only about 60-65% of the pipe whereas bunker coil is needed almost 1lakh/feet.
  • It efficiently transfers heat for preserving vegetables,meat,fish,egg in cold storages.
  • We assure 100% lifetime warranty of the fin coils manufactured by us.

Spiral FIN:

Structure:

  • Made up of Titanium,Stainless steel,Aluminium etc
  • Spiral fins are made under high mechanical tension bonding process,in which fin material is helically wound over the tube to get maximum contact of the tube and finonly one end of the fins are needed to the core tube.

Advantages:

  • This enhances it’s efficiency and enables it to endure high internal pressure.
  • Spiral fins have widespresd use in cooling or heating of water,steam,air,gases,oils and many other vapours and fluids and are highly suited to exchange heat in paper,sugar,oil refineries and power plants etc.
  • We assure 100% lifetime warranty of the fin coils manufactured by us.
